Silyl Acrylate Self polishing Polymer SPSi
Product features:
1. SPSi-100 is a high performance matrix resin product based on hydrolysis technology, the optimized polymer structure ensures the continuous & stable release of biocides. It is suitable for copper-containing formulations and can be blended with various amounts of CDP (Rosin) to satisfy different application requirements. The tin-free self-polishing antifouling coatings based on SPSi-100 resin possess 60-90 months performance (the actual antifouling performance determined by paint formulation, ships speed & activity and sailing sea area environment, etc), low VOC and excellent predictable and stable self-polishing characteristics.
Recommended biocides: Cu2O+CuPT, DCOIT/Medetomidine

Applications of different silyl acrylate self polishing polymer
* 3-5 years for ocean going ships.
(1)SPSi-100+SPRF, general and cost effective.
(2)SPSi-100+SPSi-200, higher cost and superior antifouling performance.
Shelf time of polymers: 24 months or longer, avoid lights and tightly sealed.
--- Antifouling Coatings based on Silyl Acrylate Self polishing Polymer System---
Advantages:
- The primary advantage lies in its long-term antifouling performance, with a service life ranging from 60 to 90 months and consistently stable efficacy.
- The coating formulation is highly adaptable and can be blended with dedicated SPRF polymer to reduce overall costs.
- It complies with environmental regulations, featuring low VOC content.
- It is suitable for both offshore and ocean-going applications, making it particularly well-suited for ocean-going anti fouling requirements.
Disadvantages:
- Higher costs than paint from Zinc Polymers
- The coating production process is relatively stringent, requiring strict exclusion of moisture from the system and precise control of discharge temperature below 50 celsius degrees.
- Paint storage period: 6 to 12 months.
- Packaging: 190kg,20kg drum.
- Storage: stored in a cool, dry, shady and ventilated place, avoid fire contact.
- Safety: pls. refer to our MSDS.
- Shelf life: 24 months.
