Shin-Etsu Silicone Oligomer KR510

silicon Ketone oligomer KR510

KR-510 is a methyl phenyl silicone containing methoxy Oligomer. Blended with organic resins containing methoxysilyl reactive groups, or used in methanol cure processes to impart heat, weather and chemical resistance.

Normal Attribute

Use Description

KR-510 can be used as a room temperature curing coating agent (the reaction mechanism is shown below) . Alkyl titanates are suitable curing catalysts.

React Mechanism

2≡Si-OCH3+H2O→≡Si-O-Si≡+2CH3OH

KR-510 is also used as a reactive diluent for acrylic and other organic resins. During the curing process of KR-5, 510 reacts with the active hydroxyl groups in the organic resin to form a copolymer

React Mechanism

≡Si-OCH3+HO-CR→≡Si-O-CR+CH3OH

The reaction must be heated (140-160°C), alkyl titanate can Acts as a catalyst to speed up the reaction. The coating produced by this modification process is very hard, but the adhesion to the substrate is reduced and the coating tends to be brittle.

KR-510 is prone to self-condensation during the modification reaction, so the reaction must under relatively mild conditions.

Processing Note

1) Must be tightly sealed and stored in a ventilated, cool and dark place (25°C or below, keep away from direct sunlight), keep away from heat and flame. To maintain quality, store this product in a non-humid area.

2) Also, when painting, coating, curing or drying, it is important It is to prevent the product from heating up.�� Ventilate and provide adequate ventilation.

3) Methanol is released during curing. When heat curing in a constant temperature oven, be sure to use a ventilation convection model to prevent the accumulation of explosive gases in the oven.

4) When using this product, care should be taken to prevent contact with skin and mucous membranes. In case of contact, wash immediately and thoroughly with soap and water or running water. In case of eye contact, immediately flush with water for at least 15 minutes and seek medical attention.

5) Breathing steam may cause dizziness or other unpleasant symptoms. If you have such symptoms, move to fresh air immediately.

6) Please read the Material Safety Data Sheet (MSDS) before use. MSDS can be obtained from our sales department.
