PROPERTIES / APPLICATIONS
- HTC PU 3850 has to be cross-linked with HTC Crosslinker 23 (dosage 4-7%) in order to obtain a film with an improved fullness, resistance to chemicals and high mechanical performance. The product thus obtained is suitable for concrete floors as anti -dust and/or as top-coat for epoxy resins systems.
- HTC PU 3850 and the catalyst have to be mixed for about 2-3 minutes with appropriate mechanical equipment (e.g. Helix drill).
- Cross-linked HTC PU 3850 allows to obtain a film characterized by an excellent resistance to chemicals both organic (e.g. coffe, wine, mustard, tomato sauce, etc.) and inorganic (e.g. acetone, water, detergents, ammonia, acids and bases).
- HTC PU 3850 can also be applied as a clear finish for decorative paints (e.g. Venetian stucco). Two or more coats of paints are necessary.
- It can be used to obtain anti-slip surfaces with the addition of galss microspheres (fine or large) and maintaining mixing to avoid product sedimentation.
- The support must be solid, dry, aged(if it’s of new creation), leveled, absorbent and free of oils, detergents, dust or other substances.
- It’s recommended to properly evaluate the appropriate technique (abrasion or peening) if mechanical preparation of substrate is required.
- For support of new creation or very adsorbent ones it’s suggested a pre-treatment with two or more coats of HTC PU Primer 1800 to improve the anchorage of the product.
- HTC PU 3850 can substitute epoxy systems or be painted on the surfaces to give excellent abrasionr esistance to the systems.
- HTC PU 3850 can be pigmented or the final color is given from the stained bottom.
- HTC PU 3850 and pigments have to be mixed for about 2-3 minutes with appropriate mechanical equipment (e.g. Helix drill).
- HTC PU 3850 is resistant to UV rays, because it’s an aliphatic polyurethane and not an aromatic one.
- It’s always recommended a prior mixing before use and an application temperature between 5 and 30 °C
STORAGE CONDITIONS
- The product have to be protected from frost and should be stored in closed container at temperature between 5 and 35 °C.
- The product have conditions the product won’t change its properties in a period of 12 months from the date of production.
- However, after a long period of storage, a slight separation of the product may occur, but this doesn’t chance the product efficacy.
- It’s suggested a prior mixing before use to ensure the homogeneity of the system.
