ReadElastomeric Waterproof Coatings
RAINSEAL CFR 613 is a single-component cellulose fibre reinforced aliphatic acrylic elastomeric solar reflective waterproof coating — the highest-SRI (106) coating in the Armstrong CFR/FRC family. Aliphatic film formation delivers inherent UV stability with no yellowing, reducing roof surface and interior room temperature by 8–10°C. 2000-hour UV resistance (ASTM G 154), 7-bar water permeability resistance and the longest 2-year shelf life in the range. Compliant with ASTM C-836/89 A and ISO 9001:2015. Formerly RAINPROOF CFR 613.
Figures are controlled laboratory results. Actual site performance varies with substrate, temperature, humidity, application method and workmanship — please confirm the current product datasheet before specification.
RAINSEAL CFR 613 is a solar reflective waterproof coating, a single-component aliphatic acrylic elastomeric product reinforced with cellulose fibre. With an SRI of 106, it reduces roof surface and interior room temperature by 8–10°C. This cool roof waterproof coating is diluted with up to 20% water and applied by brush, roller or airless spray.
White reflective coat that lowers room temperature by 8–10°C.
Two coats, the second applied perpendicular to the first.
Aliphatic film stays UV stable with no yellowing.
Applied by brush, roller or airless spray over a primer coat.
No leak at 7 bar in water permeability testing.
Allow 7 days full cure before water exposure.
Bridges cracks up to 2 mm, with adhesion to concrete above 1.5 N/mm².
For terrace heat and leakage together, the figures are SRI 106 to ASTM E 903, no leak at 7 bar and crack bridging up to 2 mm. Elongation at break is 200%. As a UV stable white roof coating it shows no deterioration after 2000 hours to ASTM G 154. Coverage is 50–60 sq.ft per litre per coat, and shelf life is 24 months unopened. Prime with the product diluted 2:1 with water, and allow 7 days full cure before water exposure.
Armstrong Chemicals supplies RAINSEAL CFR 613 to sites across Telangana, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, including Hyderabad, Vijayawada, Bengaluru, Kochi and Chennai.
The coating reflects a very high fraction of solar radiation, reducing roof surface and interior room temperature by 8–10°C.
Aliphatic film formation is inherently UV stable, so the white coating resists yellowing, chalking and degradation in sunlight.
The elastomeric film is reinforced with cellulose fibre. It bridges cracks up to 2 mm and shows no leak at 7 bar.
A single-component cellulose fibre reinforced acrylic elastomeric coating with aliphatic film formation — the highest stated SRI in the Armstrong CFR/FRC family, with 2000-hour UV resistance and the longest 2-year shelf life in the range.
Get a QuoteAliphatic elastomeric film formation is inherently UV-stable. No yellowing, no chalking, no degradation under 2000+ hours of accelerated UV exposure (ASTM G 154). Same aliphatic advantage found in RAINPROOF PWR 690.
No leak at 7 bar hydrostatic pressure (ASTM C 297). Bridges cracks up to 2mm (ASTM C 836) with 200% elongation. Breathable water vapour permeability — no blistering or delamination.
The longest shelf life of any FRC/CFR coating in the Armstrong range — twice the 12-month life of RAINSEAL FRC 623. Store cool and dry in original packing.
This brochure names the 2015 revision of ISO 9001 — the current quality management standard. Compliant with ASTM C-836/89 A across mechanical and water resistance testing.
The highest-SRI coating in the Armstrong CFR/FRC family, with the longest shelf life and inherent UV stability.
Solar Reflective Index 106 (ASTM E 903). Aliphatic elastomeric film provides inherent UV stability with no yellowing — reduces roof surface and interior room temperature by 8–10°C.
No deterioration, no colour fade after 2000 hours of accelerated UV exposure (ASTM G 154:2000). Adhesion >1.5 N/mm², Shore A 80 hardness — resistant to fungus, algae and micro-organisms.
No leak at 7 bar hydrostatic pressure (ASTM C 297). Bridges cracks up to 2mm (ASTM C 836). Breathable water vapour permeability prevents blistering and delamination.
Longest shelf life of any FRC/CFR coating in the Armstrong range — twice the 12-month life of RAINSEAL FRC 623. Available in 1, 5, 10, 20 and 210 litre packs.

High Performance Elastomeric Acrylic Polymer modified cementitious Waterproof System. Tough flexible hard wearing surface, resistant to UV rays. Jointless and seamless membrane.
View DetailsROOFBOND RFX PLUS 210 is a high-performance flexible reinforced waterproof coating engineered for structures under sustained water pressure. It delivers 5–5.5 N/mm² tensile strength with 120%+ elongation, bridges cracks up to 3.5mm and shows zero water penetration at a 50-metre water column, with a bond strength of 2.0 N/mm² to prepared concrete and a stated durability of 10+ years.
View DetailsSingle-component, 100% pure acrylic elastomeric waterproof exterior coating for external walls, terraces, sloped roofs, MS/ACC sheets. White and heat-reflective, self-curing, with excellent elongation and recovery to bridge existing and future cracks. Remains unaffected by salt water, soap water, mild acids and alkalies, and acts as an effective heat transfer barrier.
