POLYCRYSTAL

Single-component technical sealant for elastic, invisible bonding

Range: Technical sealants for elastic, invisible bonding

DESCRIPTION AND FUNCTION

POLYCRYSTAL is a single-component adhesive sealant based on MS Polymer™, which cures with atmospheric moisture. Its transparent, crystal-clear formula, even in thick applications, provides high elasticity, cohesion, and excellent adhesion to a wide range of materials.

It enables high-performance elastic sealing and discreet bonding, with excellent gap-filling properties.

KEY FEATURES

• Virtually shrink-free

• Flexible from –40°C to +100°C

• Neutral curing

• Odorless

• Short setting time

• Excellent adhesion to many substrates

• High cohesive strength

• Good UV resistance

• Paintable

APPLICATIONS

APPLICATION INSTRUCTIONS

1. Make sure the surfaces are clean, degreased, dry, and free of dust or loose material.

2. Apply POLYCRYSTAL to: • steel • galvanized steel • anodized aluminum • aluminum • painted surfaces • concrete • wood • glass • ceramics • natural stone • polyester • uPVC

3. Adhesion is guaranteed without primer on degreased surfaces.

4. On porous surfaces or in the presence of moisture, adhesion can be improved with a primer.

5. Apply the sealant, pressing it between the substrates or against the joint walls.

6. The product can be finished or smoothed within 10–15 minutes.

JOINT DIMENSIONS

• Joints must be designed to accommodate movement.

• Rectangular sections with a depth less than their width reduce stress.

• Adhesion must occur only on the side walls.

• To prevent adhesion to the third wall, insert a non-stick profile made of expanded polyethylene.

STABILITY AND STORAGE

• Store in a dry place between +5°C and +25°C

• Keep in the original, unopened packaging

• Shelf life: 12 months

• Protect from frost
