Topwin, a subsidiary of Wynca Group, specializes in manufacturing silicone-based functional products and stands out as a distinguished technical service provider.
Siemtcoat® serves as an efficacious agent, helping the adhesive release easier from the backing materials (paper, film, other substrates) . The users can select the optimal product for their specific application or intended purpose from our line of products, which includes solventless, solvent-based, emulsion formulations. Silicone Release Coating systems consist of base polymer, crosslinker, catalyst and other additives. Widely used in label stock, envelopes, diversified tapes, bakery paper and foodstuff package, commercial graphics art, security signage and outdoor advertising, hygienic application such as baby diaper, feminine hygiene and adult incontience products, industry application for roof coverings, pipe and thermal insulation, medical application for body electrodes, adhesive bandages, wound dressings, surgical covers, ECG, etc.
Topwin's Siemtcoat® silicone release coating systems consist of four basic components: base polymer, crosslinker, catalyst and various additives. These components can be combined in numerous ways to create customized formulations, which can be tailored to your needs through consultation with our technical teams.

Remark
. Emulsion type silicones should be agitated thoroughly before use.
. Emulsion type silicones may freeze at low temperatures, so users in colder regions should take special care with regard to storage.
. Emulsion type silicones should be storage in a closed container at +10°C to +30°C temperature.
