This information supports material selection and technical discussion. Final suitability should be confirmed under the customer’s actual formulation, substrate, process and end-use test conditions.

PRODUCT POSITIONING

Where does it fit in an application discussion?

The current TDS positions RU-3340 as a soft aliphatic PUD with clear, transparent and smooth film formation. It is a practical starting candidate when a project brief emphasizes flexibility, cold resistance, UV resistance or extensibility while keeping the finish visually clear.

Storage and handling from the current TDS

The current FAST TDS states storage in sealed original packaging at 5°C–40°C for at least one year. Reseal the package after use, use opened material as soon as practical, protect the product from freezing, and mix thoroughly before use.

BEFORE SAMPLING

Information that speeds up material matching

Model selection is rarely driven by one property. Sharing the substrate, coat position, surface target and test requirements reduces unnecessary trial cycles.

SubstrateSpecify leather, PU/PVC synthetic leather, microfiber, textile or other substrate.

Coat positionClarify base, intermediate, top coat / finish, or another layer in the coating structure.

Surface targetDescribe gloss / matte target, transparency, hand feel and any visual requirements.

Performance testsProvide the required abrasion, scratch, hydrolysis, flex, cold, aging or other test standards.

Process conditionsShare coating method, drying / curing conditions and any crosslinker or additive system already in use.

Project contextInclude end use, target market / region and any customer-specific compliance requirements.

TECHNICAL FAQ

About RU-3340
