Sikagard®-680 MY
MMA-based, highly UV-resistant decorative protective coating
Product Overview
Sikagard®-680 MY is a high-performance protective and decorative coating based on methyl methacrylate (MMA) resins, formulated for concrete, masonry and steel structures. It cures to a tough, highly UV-resistant film that guards surfaces against weathering, water absorption and chloride ingress while preserving their appearance. Available as a clear glaze that enriches exposed-aggregate and natural concrete, or as pigmented top coats in greys, white and custom shades, it lets designers protect structures without hiding their character. Typically applied in two coats (three for bright yellows and reds), it delivers both durability and finish. Space Arc Engineering, an authorized Sika distributor in India, supplies Sikagard®-680 MY for facades, infrastructure and architectural concrete where lasting protection and a retained look both matter.
Features & Benefits
- Highly UV-resistant MMA chemistry keeps colour and finish stable under sustained sun exposure
- Cuts water absorption by over 80% at 28 days, limiting moisture-driven deterioration
- Resists chloride-ion diffusion by more than 90% at 28 days for strong corrosion defence
- Unaffected by 50 freeze-thaw de-icing salt cycles for cold and exposed sites
- Clear glaze enhances exposed-aggregate concrete; pigmented grades offer decorative shades
- Fast drying — dust-dry in about 30 minutes at +20°C — speeds multi-coat application
Technical Highlights
| Coverage | Clear glaze about 0.15 kg/m² per coat; pigmented top coat about 0.20 kg/m² per coat. |
| Strength | Reduces water absorption by over 80% and chloride-ion diffusion by over 90% at 28 days. |
| Performance | Highly UV-resistant; unaffected by 50 freeze-thaw de-icing salt cycles; about 43% solids by volume. |
| Application Conditions | Apply on substrates between +5°C and +35°C at below 85% relative humidity; protect from rain for at least 1 hour at +20°C. |
| Packaging | Supplied in 20 L pails and 200 L drums; clear glaze and pigmented/custom shades. |
Applications
- Decorative UV-stable protection of architectural and exposed-aggregate concrete facades
- Coating infrastructure concrete elements exposed to weathering and de-icing salts
- Protecting masonry and concrete on commercial and institutional buildings

Frequently Asked Questions
What is Sikagard®-680 MY?
It is a high-performance MMA (methyl methacrylate) protective and decorative coating for concrete, masonry and steel. It resists UV, water and chlorides while keeping the surface’s appearance, available as a clear glaze or in pigmented shades.
How well does Sikagard®-680 MY resist water and chlorides?
At 28 days it reduces water absorption by more than 80% and chloride-ion diffusion by more than 90%, providing strong protection against moisture- and chloride-driven corrosion of reinforced concrete.
How many coats of Sikagard®-680 MY are required?
Two coats are typical, with a third recommended for bright yellow and red shades. Coverage is about 0.15 kg/m² per coat for the clear glaze and 0.20 kg/m² per coat for pigmented top coats — refer to the TDS.
Is Sikagard®-680 MY UV-resistant for outdoor use?
Yes. Its highly UV-resistant MMA formulation gives exceptional weathering resistance and is unaffected by 50 freeze-thaw de-icing salt cycles, making it well suited to exposed exterior surfaces.
