HS20

A high performance moisture curing adhesive and sealant. HS20 is a high modulus, single component, moisture-curing, adhesive and sealant based on Hodgson Hybrid Polymer Technology. Conforming fully to the
requirements of ISO 11600, it offers outstanding performance across a wide variety of industrial applications. It has excellent adhesion to glass, timber, metals,
brickwork, most plastics and concrete and does not normally require a primer.

APPLICATIONS

Suitable for sealing and bonding most common materials such as glass, timber, metals, brickwork, most plastics and concrete. Ideal for security sealing of composite PVC doors. Provides good movement accommodation and water-resistance.

• Very high strength and flexibility
• Excellent adhesion
• Paintable
• Premium quality high modulus adhesive and sealant
• Neutral system, free from isocyanates and silicones
• Highly resistant to ageing and weathering

PROPERTIES

Application temperature range: +5°C to +30°C

Curing rate: Cures at a rate of 2mm in 24 hours at 23°C @ 50% RH. Lower temperatures and drier conditions will result in a slower rate of cure.

Shelf life: 12 months in original unopened packaging at temperatures of +5°C to +25°C.

Skinning time: Skin forms after approximately 15 minutes.

Tack free time: Approximately 15minutes (23°C & 65% RH).

Working time: Approximately <15 minutes depending on conditions.

INSTRUCTIONS

Joint design: Please consult the Technical Information Sheet entitled ‘Joint design for cartridge based products’ prior to application.

Surface preparation: All surfaces must be clean, dry and free from frost, grease and loose materials. Apply primer if required. Install bond breaker to prevent bond at base of joint where necessary. Most substrates only require priming if testing indicates a need or where sealant will be subjected to water immersion after cure. Cut the top of the screw thread off the cartridge and screw on the nozzle. Cut nozzle to correct diameter for joint size. Apply using a skeleton or powered gun into the joint ensuring good contact with surfaces.In deep joints, the use of Hodgson Backing Rod is essential to ensure good joint formation. In situations where an especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed.

Tooling: Tool immediately after sealant has been applied within the working time for the product.
