Polyurethane Sealant
 
 
 
FORCON-D PU 951 : One Component Polyurethane Sealant
 
Forcon-D PU 951 has been imported from French. It is highly elastic, adhesive and paintable. Polyurethane sealant is appropriate with cold room work, cement sheet, precast sheet inducing ground work. Polyurethane can cover a joint which is 2 inches width (ratio between width and depth = 3:1)
- Color : white/gray
- 600ml./piece
- 20 pieces/carton

Why Polyurethane ?
- Tougher than silicone.
- Can be painted over while silicone can’t be(disintegration).
- Long lifetime (more than 10 years).
- Better adhesion(no more repair work)
- Various material usage such as cold room, cement sheet, precast and sealing ground joint.
- No stain on material.

Suggestion for PU usage
- Surface of material should be dry and clean, no dust and any stains such as oil or rust.
- Avoid to work in high temperature or the sun.  Air bubble may occur because a chemical reaction may happen too fast.
- PU should completely dry before painting in order to protect a swelling of paint.
- Increase adhesion by cleaningand use Primers together.
- In cast, doing on color material, make sure that the color well adhere on the material sash as Power coated color.
- Red oxide or enamel paint is not well adhere so should scratch it out.
- Clean an equipment by solvent (Toluen or Xylene) during PU is not dry. If drying, got to scratch it out
- Keep PU on room temperature or around 25 °C

Questions should know ?
- When should the work be painted ?> At least 7 days after applying PU
- What kind of paint should be ?> Water based color
- Whydosethe PUnot stick to the material? >The surface of material is not clean such as dust and oil
- How to calculate the quantify of usage? > Joint Area (width x depth) = Volume of apply

Polyurethane Joint Sealant
- Shore A = 25 (The hardness of the glue)
- Tensile Strength = 1.9 n/mm²
- Elongation at break = >800%
- Skin time = > 60min (The dry skin)
- Peel Adhesion = 120N (Glass), 150N (mortar)
- Heat Resistance = -30° to + 80°
- Maximum Joint width = 35 mm

Joint design
 General use :
 Joint up to 10 mm, width  1:1 width/depth ratio
 Joint more than 10 mm width  2:1 width/depth ratio (min depth 8 mm)
 Precast concrete :
 Joint interval distance up to 2m 2-3.5m  3.5-5m  5-6.5m    6.5-8m
 Joint width   10mm 15mm  20mm  25mm    30mm
 Joint depth   8mm 10mm  10mm  15mm 15mm
 Joint width exceeds 35mm non-sag tests are recommended
