Everbuild Contract 700T LMN Silicone extended information
Application Temperature: +5 °C to + 40 °C
Resistance
Elongation at break: >200 % ISO8339
Technical information
Shore A Hardness | 20 to 30 |
Modulus of Elasticity in Compression | <0.4 MPa |
Secant Tensile Modulus | <0.4 MPa at 23 oC (ISO8339) |
Movement Capability | 25 % (ISO9047) |
Shrinkage | <10 % (ISO10563) |
Service Temperature | -50 °C to +120 °C |
Joint Design | Maximum depth 50 % of joint width; movement capacity will be impaired if the depth of the joint is greater than the width. For maximum movement accommodation, it is recommended that: 1. The joint depth should be no less than 5 mm 2. Joint depth should be 5 mm for joints up to 10 mm wide 3. Joints above 10 mm in width should be half the width in depth up to 20mm For deep joints, reduce depth by using Fix and Fill Expanding Foam or a suitable joint backer rod. All joints should be designed so that the seal is placed in a position which does not retain water or form a water trap. Triangular fillets should be no less than 12 mm across the face and should be finished with a flat or convex face. |

APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
The surfaces must be clean, dry and free from dust, grease and other contaminants. As quality of plastics can vary, always carry out adhesion tests prior to large scale use.
Improve adhesion by wiping surface with PVCu Solvent Cleaner or white spirits (painted surfaces). Priming is generally not required, although we always advise testing small areas prior to use. Prime with Sikaflex Primer 3N for porous and Aktivator 205 for non-porous substrates if priming is to be conducted.
APPLICATION METHOD / TOOLS
Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut at an angle of 45 ° with an opening slightly larger than the gap to be sealed. Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the trigger and keeping the gun at a constant angle to the surface being sealed. To ensure a proper bond, always smooth the sealant down with a spatula or piece of wood An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5 minutes of application.
