 Applications of Premium Grade Boron Oxide CAS NO 1303-86-2  

● Specialty glass such as LCD/TFT screens, fiber optics, heat resistant glasses.

● It is an additive in production of high strength and heatproof ceramics and refractory materials. Temperature, corrosion resistant materials.

● As a catalyst for organic processing, the additive of lubricant chemical used in high temperature. It can be also used in environmental protection.

● Used in production of alloy and steel in metallurgical industry.

● Synthesizing many boron compounds.

 

Safety instructions:

The boron oxide is considered toxic. It is harmful to bodies health by swallowing, breathing in, eyes contacting, skin contacting. To bring it into contact with eyes or skin will lead to irritation. To swallow it will lead to irritating alimentary canal. To inhale it will lead to irritation of respiratory tract. The highest allowable concentration is 15mg/m3 (OSHA) in working place. Wear safety-protective glasses, dust-proof gauze musk, rubber gloves during handling it.

 

Remark : This boron oxide has been strictly quality-checked and granted for (exit-works) delivery. We can provide you the COA after the goods out of factory. If special request for Mesh Size, please kindly let us know. By the way, when you export this powder to the countries of European, we can supply you the Reach Report for supporting.

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.

Second, basic performance.

Methyl tetrahydrophthalic anhydride, referred to as MTHPA, MeTHPA, has two isomers, namely 4-methyltetrahydrophthalic anhydride and 3-methyltetrahydrophthalic anhydride, having a melting point of 65 °C and 63 °C. It is rarely used as a curing agent alone. The actual commodity is a liquid mixture that isomerized to various isomers. The molecular weight is 166.17, and light yellow color, transparent oily liquid, relative density of 1.20 - 1.22. Freezing point < -20 °C. The boiling point is 115-155 °C. Viscosity (25 °C) 40 - 80 mPa · s. The refractive index is 1.4960 to 1. 4980. The anhydride group content is ≥ 40%. The neutralization equivalent is 81-85. The flash point is 137 - 150 °C. Soluble in acetone, ethanol, toluene, etc. It has good stability in air and is not easy to precipitate crystals. Low toxicity, LD502102mg/kg.
