Polyaspartic Polyurea High-Gloss Grout Sealant
Polyaspartic Polyurea High-Gloss Grout Sealant PS700C is a high-performance, two-component sealant based on aspartic acid ester resin and aliphatic isocyanate. It offers outstanding UV resistance, fast curing at low temperatures, and a high-gloss finish (85° at 60°). With excellent stain, water, and chemical resistance, it ensures long-lasting protection and aesthetic appeal for both indoor and outdoor grout applications.
Product Overview
PS700C is a two-component polyaspartic polyurea high-gloss grout sealant developed for durable and decorative surface protection. It is formulated with aspartic acid ester resin as Part A and an aliphatic isocyanate curing agent as Part B, together with silica, pigments and other functional additives.
The cured material combines a glossy appearance with strong resistance to water, stains, UV exposure and acidic or alkaline conditions. Its balanced hardness and flexibility help the cured film withstand thermal expansion and contraction while maintaining durable surface protection.
With a measured gloss of 85 at 60°, Shore D hardness of 63 after 7 days, tensile strength of 21.27 MPa and elongation at break of 129%, PS700C provides a combination of surface appearance and mechanical performance for demanding grout sealing applications.
Key Features & Benefits
High UV and Weather Resistance
PS700C is designed for non-yellowing and non-powdering performance. It provides long-lasting gloss and color retention under direct sunlight, making it suitable for applications exposed to outdoor light and weather conditions.
High-Gloss Decorative Finish
The cured surface provides a measured gloss of 85 at 60°, helping create a clean, smooth and visually attractive finish.
Fast Curing and Rapid Return to Service
The product has a working time of approximately 30–35 minutes and a surface dry time of approximately 50 minutes. Its fast curing characteristics support same-day excess removal and rapid foot traffic according to the TDS.
Excellent Stain Resistance
PS700C demonstrates strong resistance to common staining substances. Testing with red wine, black tea, soy sauce and vinegar recorded a stain resistance grade of 0.
Water and Chemical Resistance
After 168 hours of water resistance testing, the cured material showed no blistering, no peeling and no significant discoloration. It also demonstrated resistance to 5% sodium hydroxide and 5% sulfuric acid under the specified test conditions.
Balanced Hardness and Flexibility
The cured material achieves Shore D hardness of 63 after 7 days while retaining 129% elongation at break. This combination provides durable surface protection while accommodating movement associated with thermal expansion and contraction.
Typical Application Areas
PS700C is designed as a high-gloss grout sealing material where appearance, stain resistance, water resistance and surface durability are important considerations.
Potential application considerations include:
- Grout sealing applications
- Decorative grout protection
- Areas requiring a high-gloss surface finish
- Surfaces exposed to water or moisture
- Applications requiring resistance to common stains
- Outdoor applications requiring UV and weather resistance
- Areas subject to acidic or alkaline exposure
The actual suitability of PS700C should be evaluated according to the substrate, grout system, service conditions and project requirements.

Product Formulation
PS700C is supplied as a two-component system:
- Part A: Aspartic acid ester resin
- Part B: Aliphatic isocyanate curing agent
- Other components: Silica, pigments and functional additives
The combination of an aspartic acid ester resin and aliphatic isocyanate curing agent provides the basis for the product's fast-curing and weather-resistant polyaspartic polyurea system.
Curing and Performance
PS700C is designed to provide a practical balance between working time and rapid curing. With a working time of 30–35 minutes, the material provides a defined application window before developing its final cured properties.
The TDS reports a surface dry time of approximately 50 minutes and an actual drying time of approximately 5 hours. The fast reaction mechanism also supports rapid return to service and same-day excess removal under appropriate conditions.
Surface Protection Performance
Once cured, PS700C provides a combination of decorative appearance and protective performance.
Its high gloss, stain resistance and yellowing resistance make it suitable where the appearance of the finished grout is important. Its water resistance and resistance to both acidic and alkaline test media provide additional protection in environments where the grout may encounter moisture or chemical exposure.
The product also exhibits a tensile strength of 21.27 MPa and elongation at break of 129%, providing a useful balance between strength and flexibility.
Packaging
PS700C is supplied in:
420 g net weight / 400 mL per tube
The tube format provides a convenient packaged form for grout sealing applications.
