PRODUCT DESCRIPTION
YH SPU-301 is a one component pitch free polyurethane based waterproof coating. It cures by reaction with atmospheric moisture to form a tough, elastomeric, waterproof membrane.
PRODUCT DATA
FEATURES
1. Pitch free formulation.
2. One component. Ready to apply direct from the can (no mixing required) .
3. Good rubber elasticity and resilience, high tensile strength, strong resistance to the deformation of base layer (shrinkage and cracking).
4. Good bonding property, strong adhesion.
5. Excellent water and corrosion resistance.
6. Excellent low temperature flexibility, -35 ºC low temperature bending without cracking.
7. Low VOC, environmental friendly.
APPLICATION
Apply to different basements; washroom, kitchen, balcony, water pool, parking lot etc.
Apply to non-exposed roof waterproof engineering.
Consumption
When dry film thickness is 1.0mm, the dosage is about 1.6 kg/m2-1.8 kg/m2
1. Base treatment: The base should be flat, solid, dry, no sharp convex, honeycomb, pitted and peeling, no pollution, and free from dust and dirt. It is recommended to use special primary treatment agent while the surface is porous or it is in the high temperature and high humidity or exposure environment construction.
2. Detailing: Make the additional layers in detail node like deformation joint, water outlet, concave and convex corners. Pre-install reinforcement materials and then brush these places for 2-4 times until thoroughly penetrating into it. Keep no folds and edge warp.
3. SPU-301 PU coating: Use rubber/metal scraper to brush or spray evenly 2-3 times. The first time should apply a thin coating film to seal the base surface's pinholes, then carry out the next coating when the previous coating is dry, normally need 12h(in low temperature shall extend the dry time), the brushing direction should be vertical to the previous one.
4. Tip and edge seal: Add-coating for sealing.
5. Protection layer: After the acceptance of the waterproof layer of the coating film, the protective isolation layer can be carried out according to the relevant specifications or design requirements.
