    • Introduction:

      DYC-731 SPU Overstrength Elastic Waterproofing Coating (Herein after referred to as "SPU ") is developed and manufacturered by latest technology introduced by DAYU from abroad.
      DYC-731 is one-component water solidified polyurethane waterproofing coating, composed of main ingredients like isocyanates, polyethers, with some additives. It is flexible waterproof coating by chemical reaction.
      During construction, get the coating mixed uniformly, then brush it on the base directly. If necessary, added no more than 10% clean water(in terms of weight) into the coatings and blend them well by motor stirrer before coating the base.

      Features:

      • Directly construction can be applyed to the moisture or dry substrate.

      • Strong adhesive to substrate,high polymer materials in the coatings can penetrated into the micro crack of the substrate.

      • Good flexibility of the coatings,high adaptability to the crack or expansion of substrate,excellent tensile property.

      • Environmental freindly,non-toxic and odor free,harmless to human beings.4.Good weather-resistance.Not to flow under high temperature,no cracking under low temperature,excellent anti-aging-ability,grease-proof,abrasive-resistance,ozone-resistance, acid resistance.

      • Coating film is close-grained without cracking,pinholes,nor bubbles.small vapor permeability.It can be waterproofing and vapor isolation function.

      • Easy to construction,shorten the construction time,maintenance convinently.

      • Can be customized with different color according to the requrements.

      • Light weight,no additional weight load to building.

      Interarea treatment
      The interarea should be firm, smooth, solid, no sharp angles, without any dust, oil and obvious water damage. Internal and external corner should be made circular with cement mortar or sealant. Cracks and surface irregularities need to be filled by sealants.

      Interarea Treating agent

      To improve adhesion strength, we usually brash basement agent before construction. Primary treatment agent can be diluted with water in the site preparation coating which recommend amount of water to 50% is appropriate. The dosage of treatment agent is about 0.3/.Recommended thickness is 1.5 mm-2.0 mm. The coating should be brushed 3-4 times. After the previous coating become dry, construct the next layer each time (usually spaced 8 hours). Each brushing direction should be perpendicular with the last brushing.
