GENOMER* 3486 – For wood coating formulations 

If you've been searching for the perfect UV oligomer for your wood coating formulations, then look no further. Whether you need a topcoat with a great appearance or a tough, resilient coating for demanding wear conditions, RAHN's GENOMER* 3486 will provide the solution you are looking for.

There is a multitude of UV oligomer choices available to the formulator. Choosing the right one to use for your application can be a painstaking process. In addition to performance properties, other considerations such as cost, and bio-renewable content also play a role in the final decision.

The good news is that RAHN has a versatile product that will make the choice much easier: GENOMER* 3486. This tetra-functional polyester acrylate provides toughness and resiliency without the higher cost normally associated with high performance oligomers. It offers excellent scratch and abrasion resistance, and its chemical resistant nature allows it to stand up to the harsh cleaning solutions on the market today

In addition to its superior performance characteristics, the viscosity of GENOMER* 3486 is just 500 mPa*s at room temperature making it ideal for coatings applied by roll coater or even spray or vacuum. Typically, a high performing oligomer would have to be reduced dramatically with monomer to achieve spray viscosity but with GENOMER* 3486, oligomer content can be maintained at a much higher level, making the most of the performance properties that this resin brings.

GENOMER* 3486 is also a good for wetting pigments and is compatible with inert gloss- and texture-control agents such as talc and silicas, making it an excellent choice for use in recoatable, sandable UV sealers and primers.

If you're looking to develop a new wood coating or improve an existing formula, GENOMER* 3486 provides a great foundation to build on. Give it a try!

There's nothing like a velvet soft touch

Formulating a viable soft touch coating has consistently been an elusive target in energy-curing applications. Soft feel is a very subjective property that is affected by a formulation's glass transition temperature and the specific fillers used to generate this coveted texture. Typically, waxes improve the surface feel while silica-based matting agents combined with higher Tg acrylates increase smoothness and scratch resistance. A balanced combination of the two surfaces can produce the desired haptic quality with good scratch resistance performance.

However, high inherent crosslinking and limited shrinkage (versus solvent-based coatings) make it challenging to formulate low gloss and soft feel energy-cured coatings. In addition, the high filler loading necessary to achieve soft touch can result in lack of good coating flow and poor scratch resistance.

GENOMER* 7287 – the provider of "soft" solutions for your challenges

If this is the challenge confronting you, RAHN may have help for you. Low viscosity GENOMER* 7287 combined with the correct choice of fillers can bring this problem to a very "soft" conclusion. It works wonders utilizing only small amounts of an aerogel silica and matting agent to produce a respectable soft touch and low gloss while maintaining excellent scratch resistance.

See what GENOMER* 7287 can do for you in terms of soft touch and reduced gloss performance. It's a hard world out there. Any opportunity to add a bit of velvety softness to it is a beautiful thing!
