Aliphatic Polyurethane Acrylate Oligomer Supplier & Product Solutions

Aromatic polyurethane acrylates are typically derived from toluene diisocyanate (TDI) or methylene diphenyl diisocyanate (MDI). Under solar ultraviolet exposure, the aromatic ring oxidizes into absorbing quinoid units that induce yellowing, surface microcracking, and loss of gloss. In contrast, Ever Ray's aliphatic urethane acrylates use saturated diisocyanates (such as IPDI and HDI) that do not form UV-absorbing chromophores. This chemistry ensures exceptional color stability, making them the standard choice for automotive exterior films, clear plastic topcoats, optical discs, and outdoor architectural coatings.

Oxygen inhibition occurs when atmospheric triplet oxygen diffuses into the curing film faster than radical generation, forming non-propagating peroxy radicals that leave a tacky surface. To counter this without inert nitrogen purging, we recommend incorporating copolymerizable amino acrylate oligomers or active amine co-initiators. These amine donors rapidly abstract hydrogen from peroxy radicals, regenerating active alkyl radicals that continue chain growth and accelerate surface cure on high-speed lines.

Our 40,000 m² factory operates under an integrated ISO 9001 and ISO 14001 Quality Management System governed by automated DCS reactor tracking. Every production batch is evaluated in our analytical testing laboratory for Brookfield viscosity, color (Gardner scale), acid value, water content via Karl Fischer titration, and residual NCO via FT-IR. Only batches that fall within narrow technical specification windows are cleared for release, with every international shipment accompanied by an authentic Certificate of Analysis (COA).

Yes. Low-surface-energy substrates such as PP, PE, and COP pose significant adhesion challenges due to their non-polar surface characteristics. Our polymer synthesis team can chemically graft polar adhesion-promoting groups—such as carboxyl, phosphate, or chlorinated polyolefin segments—directly into the polyurethane acrylate backbone. Combined with low-shrinkage monofunctional diluents, this modification enhances interfacial thermodynamic wetting and achieves cross-hatch adhesion scores of 5B without corrosive primers.

Standard packaging options include 20kg UN-certified fluorinated plastic drums, 200kg tight-head steel drums with nitrogen headspace blanketing, and 1,000kg intermediate bulk containers (IBCs). Our standard minimum order quantity for established grades is 200kg (one drum), with 1kg to 5kg laboratory trial samples available for rapid courier dispatch. For global accounts, we routinely fulfill under FOB, CIF, DDP, and CFR terms directly from Jiangmen and Shenzhen ports.
