H-POLYMER STP - Transparent Polymer
Product description
Moisture-curing, single-component, high-quality STP (silane-terminated polyurethan) based adhesive for professional users. H-polymer STP transparent is designed for expansion joints and seals as well as for elastic bonding. It is a versatile product for interior and exterior work and craftsmen in various fields. Examples of application include window and door joints, bonding of building elements, joints of finished building elements and plasterboard, applications in kitchens and bathrooms. Joint can be painted after curing (also with watercolours). The bonding is permanent, completely resistant to changing weather conditions and UV radiation.
USAGE / EXAMPLE OF USE
- bonding and sealing of all construction materials: natural stone, wood, concrete, metal, brick, glass, ceramics, plaster, polyurethane, plastics, chipboard etc.
- flexible bonding in vibrating elements
- bonding of elements of galvanized steel sheets, brass and other metals

APPLICATION / HANDLING
The surface for bonding with H-polymer STP transparent should be clean and free of dirt, dust, fat, grease, rust and other substances that impair adhesion. The adhesive does not require a primer, however if some surfaces do need a primer. Prior to application of the adhesive protect edges with masking tape. Apply using manual or pneumatic guns. The adhesive may be smoothed with a spatula for spreading silicone dampened in silicone wetting preparation or soap solution. Use plastic or stainless-steel tools. The adhesive cures through a reaction with moisture in the air and therefore the seal should be performed in conditions that allow access of air.
CLEANING
After use, wipe the tools with a paper towel and clean with solvent.
