Product attributes

Lt-619 unsaturated polyester resin is a kind of BMC special resin.It has good heat resistance, high mechanical strength, good curing and so on.The surface of the resin is bright, flat, and excellent in electrical energy. It can be used in combination with low shrinkage resins, which can improve the toughness of the product.

The main application

Lt-619 unsaturated polyester resin can be widely used in electrical components, industrial components, residential equipment, automobile parts and other fields.

Use instructions and precautions.

1, LT - 619 resin with 1 ^ - 8987 resin, used in the production of high roughness moulded products.

2. In general, the mixing ratio of lt-619 resin and LT-LPA-8 resin is 60:40, which can also be adjusted according to the actual situation.

3. According to the size requirement of the final product, we can add 300ppm~ 600ppm to benzoquinone in the formula (based on the total amount of resin and low shrinkage additive).

4. In the summer, to improve the fertilizer storage period of premix and to add stabilizer in the right amount.

Storage conditions

1, before using resin should be in the original packaging (to avoid open the barrel and barrel broken damage) to store below 25 ℃ dry room and keep the bucket tightly sealed to prevent moisture intrusion, tighten the cover.

2. The increase of temperature and light exposure will significantly reduce the storage period, and avoid direct sunlight and away from heat source.

3. Unsaturated polyester resin containing styrene should be kept away from open flame when it is stored in |.

4. If the ingredients in the resin are not properly used, they will cause harm. Avoid contact with skin and eyes, and wear necessary protective clothing and clothing when using.Product safety instructions refer to the company's "resin safety instructions (MSDS)".
