Reaction property：

² RK-311 is an alkyl trialkoxy silane. The trialkoxy group is hydrolyzable, and after hydrolysis, the silicon hydroxyl group (Si-OH) is easily condensed to form a very stable silico-silicon structure (-Si-o-Si -). There are many factors affecting hydrolysis and condensation, the most important factors are: PH value, concentration, solvent, temperature and catalyst.

² RK-311 is hydrolyzed to form silanol, which can react with the hydroxyl group on the surface of inorganic materials such as quartz, clay, and silica to form a hydrophobic layer.

² The alkoxysilane in RK-311 can react with hydroxy-terminated alkoxysilane under the action of catalyst. Then, using the hydrolyzable condensation of alkoxysilane, elastomers with good mechanical properties can be formed

Product application:

l Dealcoholized single component room temperature vulcanized silicone rubber crosslinking agent, silicone resin coating.

l RK-311 transparent coatings obtained by hydrolyzing condensation are widely used as surface hardening, wear-resistant and solvent resistant coatings for plastic products such as sunlight panels, eye lenses, sunglasses and automotive taillights.

l Sol-gel for the production of organic and inorganic hybrid materials. RK-311 can be used alone, or with other silicates, or other organosilanes co-hydrolysis, through the sol-gel process, can be adjusted by hydrolysis PH value, temperature and concentration and other conditions to achieve a variety of required properties.

l Surface hydrophobic agent for inorganic materials

l When used as filler pigment treatment agent, the recommended addition amount of RK-311 is 0.5 to 1.0% of the total solid content. When used as powder filler treatment agent, RK-311 can be directly added to the powder mixer to treat the filler. RK-311 can also be used with methanol or isopropyl alcohol diluted to 10%, in general, silane relative to the total solid content of 0.5 to 1.0%.

l The pigment dispersant can be added directly to the resin with the pigment to improve the dispersion of the pigment in the resin.

Product security, handling and storage:

The container should be sealed after opening to prevent water vapor from entering and producing hydrolysis. Stored in the original unopened container at room temperature, this product has a shelf life of one year from the date of production. After passing the test, the buyer will decide whether to continue to use the expired product.
