PROMOPUR W is a two-component polyurethane adhesive used in the underground excavations, mining and construction industry. In the 'W' version, it is a specialized adhesive used mainly for sealing, filling and reinforcing wet and heavily watered seams. Additionally, PROMOPUR W may be used for sealing and securing various types of building structures and tunnels located in the close vicinity or directly under the water tanks.
After thorough mixing of two components PROMOPUR W is a ready-to-use product. The ratio of the two components is strictly specified by the manufacturer, which guarantees maintaining the declared parameters and the properties of the final mass. PROMOPUR W adhesive contains a polyol mixture, which is component A and an isocyanate curing agent (component B). Each of the components is a viscous liquid with different physico-chemical parameters. Component A has a straw to yellow colour, while component B is brown. Highly hygroscopic component B, induces polymerization of the adhesive without the need for any other external factor.
PROMOPUR W adhesive provides reduced emissions of volatile organic compounds (VOC). It does not contain foaming agents that significantly deplete the ozone layer, which is pursuant to EU Regulation (EC) No. 1005/2009 of 16 September 2009.
PROMOPUR W is a two component polyurethane adhesive intended for using in moist / highly wet working seams. The adhesive has a Hygienic Certificate issued by the National Institute of Hygiene (PZH), which confirms that PROMOPUR used in accordance with manufacturer’s instructions does not adversely affect health and the environment.
High quality and efficiency of the adhesive has been confirmed by positive assessment issued by LABOREx research laboratory. Positive evaluation of PROMOPUR adhesive resulted in the approval issued by the Mining Authority for using it in underground mining, especially in humid and heavily watered areas. It has been confirmed by OBAC certificate of conformity.
