Foster 30‑36

 At Rubo Al Hail International Enterprise L.L.C., based in Muscat, Oman, we are proud to supply the original Foster 30‑36 Sealfas® Coating — an essential component in HVAC system insulation where reliability, fire safety and longevity matter. As a leading AC spare parts supplier Muscat, Oman, we understand that specifying the right finishing and protective coatings for ductwork and chilled‑water systems is critical for performance, hygiene and compliance.

This coating serves as a protective finish for insulation on air‑conditioning ducts and cold water piping: when applied in two coats with reinforcing fabric embedded between coats it delivers exceptional durability, reducing maintenance costs and extending equipment life. The product is especially valuable in commercial installations and industrial refrigeration locations where elevated humidity, temperature extremes and high usage cycles place extra strain on system components.

Technical Specifications & Insights
The Foster 30‑36 coating is a white, water‑based formulation that is halogen‑free and designed for indoor use on high‑performance insulation. It is abrasion‑resistant and washable — meaning that once the HVAC system is installed and commissioned, cleanup and servicing are simple. It has excellent adhesion to substrate surfaces and remains stable when exposed to high humidity or elevated temperatures. The flame spread and smoke‑developed ratings are very low (for example flame spread ~10, smoke developed ~5 on ¼″ cement board test) making it compliant with fire‑safety regulations for HVAC installations. It is compatible with polystyrene, polyurethane foams and fibrous insulation facings. The product also meets MIL‑DTL‑3316C Class 1 Grade A and NFPA 90A/90B 25/50 requirements, giving you confidence in safety performance.
In practical terms this means you can wrap and finish your HVAC duct systems with a product that complements the overall system build quality, supports good indoor‑air quality (IAQ) control and ensures the end‑user environment remains protected from corrosion, moisture ingress and mechanical damage.
