As UV curing technology expands into 涂料, inks, adhesives, and electronics, formulators face growing pressure to reduce reliance on petroleum‑based raw materials. The challenge has always been finding a renewable 单体 that delivers the same – or better – performance than conventional acrylates.
SINOMER® ISDA (Isosorbide Diacrylate) changes that. Derived from isosorbide – a biomass‑sourced building block – this difunctional acrylate combines high reactivity, low shrinkage, low irritation, and excellent adhesion. It is a drop‑in capable 等效替代 HDDA, TMPTA, and other traditional 单体s, while significantly improving the environmental footprint of your UV/EB formulations.
Unlike HDDA or TMPTA, which are 100% fossil‑based, SINOMER® ISDA uses renewable feedstocks. This means:
Lower carbon footprint per kilogram of 单体
Reduced dependency on volatile petrochemical markets
Support for your company’s sustainability goals (ESG, Green Label)
ISDA cures rapidly under UV or EB irradiation, developing surface hardness comparable to TMPTA but with much lower skin irritation. The rigid isosorbide ring structure imparts excellent mechanical strength to cured films – ideal for scratch‑resistant 涂料 and durable inks.
One of the biggest pain points with high‑functional acrylates is volume shrinkage, which leads to warping, poor adhesion, and stress cracking. ISDA’s unique bicyclic ring structure reduces shrinkage during polymerization, giving you better dimensional stability – especially important for thin films, 3D printed parts, and precision 涂料.
Conventional 单体s like TMPTA and HDDA are known skin sensitizers. ISDA offers a much milder profile, making it safer for production workers and expanding its use into consumer‑friendly applications such as nail gels and medical device 涂料.
The polar nature of the isosorbide backbone promotes strong bonding to plastics (PC, PET, ABS), metals, and glass – often without the need for additional adhesion promoters.

SINOMER® ISDA delivers a unique balance: renewable origin, fast cure, low irritation, and low shrinkage – all in one 单体.
Thanks to its versatility, ISDA fits into a wide range of UV/EB curable systems:
UV plastic 涂料 – ideal for electronics housings, automotive interior parts, and consumer goods
UV printing inks – offset, screen, and flexo inks that require high scratch resistance and adhesion on films
UV adhesives – structural bonding where low shrinkage and high green strength are needed
Photosensitive resins – for printed circuit boards, solder masks, and 3D printing
Decorative and architectural 涂料 – wood, metal, and glass finishes with low VOC

SINOMER® ISDA is miscible with most acrylate oligomers (epoxy acrylates, polyurethane acrylates, polyester acrylates) and common 单体s (IBOA, THFA, NVC, TPGDA). It can be used as a reactive diluent or as a primary 单体, typically at 10–50% of total formulation.
Packaging options: 25 kg plastic drum or 200 kg steel drum.
Storage: Keep in a dry, well‑ventilated area away from light and heat. Shelf life is 12 months under recommended conditions (5–35°C).
Switching to a bio‑based 单体 doesn’t mean sacrificing performance. SINOMER® ISDA proves that renewable chemistry can deliver fast cure, high hardness, low shrinkage, and low irritation – all while reducing your environmental impact.
