Is Epoxy Resin Heat Resistant?

Is epoxy glue heat resistant?

1. Epoxy resin AB adhesive classification: can be divided into epoxy resin filling adhesive, epoxy resin thermal conductive adhesive, epoxy resin sealant, epoxy resin high temperature adhesive, epoxy resin fast-drying adhesive.

2. Heat resistant epoxy glue is a fast curing series, clear and viscous epoxy resin adhesive. It can be cured at low or normal temperature with fast curing speed. After curing, the bonding strength is high, the hardness is good and the resistance is good. After curing, it has good acid and alkali resistance, moisture-proof, waterproof, oil-proof and dust-proof functions, moisture-heat resistance and atmospheric aging resistance. After curing, it has excellent electrical and physical properties of insulation, compression, bonding strength. So how high temperature can the epoxy resin AB resist? For different product processes, the temperature resistance is also different, 100 degrees, 200 degrees, 300 degrees, 1000 degrees and so on.

Tibolone

Tibolone Basic Info

Product name: Tibolone

Alias: LIVIELLA; LIVIAL

CAS: 5630-53-5

EINECS: 227-069-1

Assay: 99% min.

MF: C21H28O2

MW: 312.45

Appearance: White or off-white crystal powder

Grade: Pharmaceutical Grade

Storage: Shading, confined preservation

Usage: It is a synthetic hormone-type drug which is used mainly for hormone replacement therapy in post-menopausal women.

 

Tibolone Product Detail

Tibolone, sold under the brand names Livial and Tibofem among others, is a medication which is used in menopausal hormone therapy and in the treatment of postmenopausal osteoporosis and endometriosis. The medication is available alone and is not formulated or used in combination with other medications. It is taken by mouth.

 

Side effects of tibolone include acne and increased hair growth among others. Tibolone is a synthetic steroid with weak estrogenic, progestogenic, and androgenic activity, and hence is an agonist of the estrogen, progesterone, and androgen receptors. It is a prodrug of several metabolites. The estrogenic effects of tibolone are selective to certain tissues, with such effects in bone, the vagina, and the brain, but not in the uterus, breast, or liver.

 

Tibolone was developed in the 1960s and was introduced for medical use in 1988. It is marketed widely throughout the world, for instance in Europe. The medication is notably not available in the United States or Canada. It is a controlled substance in Canada, with the classification of an anabolic steroid.

 

Tibolone Application

All the information we provide is for reference only, please use drugs according to professional advice

 

Tibolone is used in the treatment of menopausal symptoms like hot flashes and vaginal atrophy, postmenopausal osteoporosis, and endometriosis. It has similar or greater effectiveness compared to older menopausal hormone therapy medications, but shares a similar side effect profile. It has also been investigated as a possible treatment for female sexual dysfunction.

 

Tibolone reduces hot flashes, prevents bone loss, improves vaginal atrophy and urogenital symptoms (e.g., vaginal dryness, dyspareunia), and has positive effects on mood and sexual function.The medication may have greater benefits on libido than standard menopausal hormone therapy, which may be related to its androgenic effects. It does not cause increased endometrial proliferation and is associated with low rates of vaginal bleeding and breast pain.

 

A 2015 network meta-analysis of randomized controlled trials found that tibolone was associated with a significantly decreased risk of breast cancer (RR = 0.317). The decrease in risk was greater than that observed with most of the aromatase inhibitors and selective estrogen receptor modulators that were included in the analysis. However, paradoxically, other research has found evidence supporting an increased risk of breast cancer with tibolone.

 

Tibolone Side Effects And Prevention

A report in September 2009 from Health and Human Services' Agency for Healthcare Research and Quality suggests that tamoxifen, raloxifene, and tibolone weight loss used to reduce the risk of breast cancer significantly reduce the occurrence of invasive breast cancer in midlife and older women, but also increase the risk of adverse effects.

 

Tibolone can produce androgenic side effects such as acne and increased facial hair growth. These side effects have been found to occur in 3 to 6% of treated women.

 

A 2016 Cochrane review has been published on the short-term and long-term effects of tibolone, including adverse effects.

Cationic Surfactant

Do you want to buy cationic surfactant?

Cationic surfactants are mainly nitrogen-containing organic amine derivatives. Since the nitrogen atoms in their molecules contain lone pair electrons, they can bind hydrogen with hydrogen molecules in the acid molecule and bring the amino group to positive charge. Therefore, they have good surface activity in acidic media; they easily precipitate in alkaline media and lose surface activity. In addition to nitrogen-containing cationic surfactants, there are also a small number of cationic surfactants containing elements such as sulfur, phosphorus, and arsenic.

 

Palmity Tri-methyl Ammonium Chloride

Chemical Formula: C21H46ClN

CAS No.:112-02-7

Dangerous Grade: Non-dangerous

 

Stearyl Tri-methyl Ammonium Chloride

Chemical Formula: C21H46ClN

CAS No.: 112-03-8

Dangerous Grade: Non-dangerous

 

Cationic surfactants have a long history of industrial use, and demand has been increasing rapidly year by year, but due to its special use as fungicides, fiber softeners and antistatic agents, it has a small demand compared to anionic and non-ionic surfactants. The development and use of cationic surfactants in China started very late, but its development rate is faster.However, due to the narrow range of application of cationic surfactants and the small amount of use, the output is very small. Until 2002, the annual output was still only a few thousand tons, which was less than 1% of the total output of various surfactants.

 

Cationic surfactants generally have good emulsifying, wetting, washing, sterilizing, softening, antistatic and anti-corrosive properties. Due to their special properties and applications, they have a good development potential both in industrial and civil applications.

 

Cationic surfactants have good bactericidal, softening, anti-static, anti-corrosive, and certain emulsifying and wetting properties, and are often used as phase transfer catalysts. However, such surfactants are rarely used as detergents alone because many substrates are usually negative in aqueous solutions, especially alkaline aqueous solutions. In addition, the main application areas of these surfactants are not like other surfactants, which are used to reduce the surface tension,  its structural characteristics make them used for other special aspects. Based on the chemical structure of cationic surfactants, they can be divided into four types: amine salt type, quaternary ammonium salt type, heterocyclic type, and barium salt type.
