Technical documents and conditions of use

See the technical documents below for specification sources and conditions. Verify the model and document version before application. Specification sources

See page 16 of the handbook for this model. This selection handbook is not an individual model TDS or SDS. Confirm the formal specification and safety documents with the technical team.

Check performance and service-life statements against the applicable reports, specimen preparation, test standards and service conditions. Unverified service-life figures are not durability guarantees; site photos do not replace film-thickness measurements or project acceptance records.

Selection guide

CY810 is one of the hardener options for low temperature construction; The minimum construction temperature, pot life, touch-dry, repainting and final performance must be confirmed by complete formulations, ground conditions and field templates.

Work at low temperatures requires complete validation.

Low-temperature construction polyaspartic polyurea cannot be judged solely by the name of hardener. The environment and substrate temperature affect viscosity, mixing, leveging, touch-dry, repainting and final curing, and the dew point should be checked for water content at the substrate prior to construction, with minor tests and field templates based on the complete formulation.
