    Other Details



    FACTORY SHOW-11 Guangdong Pustar Adhesives & Sealants Co., Ltd. is a professional manufacturer of polyurethane sealant and adhesive in China. The company integrates scientific research, production and sales. It not only has its own R&D technology center, but also cooperates with many universities to build a research and development application system. FACTORY SHOW-22 The self-owned brand “PUSTAR” polyurethane sealant has been highly praised by customers for its stable and excellent quality. In the second half of 2006, in response to changes in market demand, the company expanded the production line in Qingxi, Dongguan, and the annual production scale has reached more than 10,000 tons. 

    FACTORY SHOW-33 For a long time, there has been an irreconcilable contradiction between technical research and industrial production of polyurethane sealing materials, which has restricted the development of the industry. Even in the world, only a few companies can achieve large-scale production, but because of their super strong Adhesive and sealing performance, its market influence is gradually expanding, and the development of polyurethane sealant and adhesives surpassing traditional silicone sealants is the general trend. 

    FACTORY SHOW-44 Following this trend, Pustar Company has pioneered the “anti-experiment” manufacturing method in the long-term research and development practice, opened up a new road to large-scale production, cooperated with a professional marketing team, and has spread all over the country and exported to the United States, Russia and Canada. And Europe, the application field is popular in automobile manufacturing, construction and industry. 


    Hose sealant use steps

    Expansion joint sizing process steps
    Prepare construction tools: special glue gun ruler fine paper gloves spatula knife Clear glue utility knife brush rubber tip scissors liner
    Clean the sticky base surface
    Lay the padding material (polyethylene foam strip) to ensure that the depth of the padding is about 1 cm from the wall
    Pasted paper to prevent sealant contamination of non-construction parts
    Cut the nozzle crosswise with a knife
    Cut the sealant opening
    Into the glue nozzle and into the glue gun
    The sealant is uniformly and continuously extruded from the nozzle of the glue gun. The glue gun should move evenly and slowly to ensure that the adhesive base is fully in contact with the sealant and prevent bubbles or holes from moving too fast
    Apply clear glue to the scraper (easy to clean later) and modify the surface with the scraper before dry use
    Tear off the paper

    Hard tube sealant use steps

    Poke the sealing bottle and cut the nozzle with proper diameter
    Open the bottom of the sealant like a can
    Screw the glue nozzle into the glue gun
