The advanges of HPMC & MHEC in dry mix mortar products
November 22nd 2024
The application of EIFS (Exterior Insulation Finish System) in Europe and the United States has a history of more than 60 years and has accumulated rich experience, but there have also been some problems. After the outbreak of the oil crisis in the 1970s, due to the need for energy saving, the external wall thermal insulation and decoration technology was popularized in both public buildings and civil buildings. The market and technology of this industry have made great progress. But by the late 1980s, many thermally insulated buildings had problems with water leakage. Of course, water leakage is caused by many reasons, among which the aging and cracking of the adhesive should be one of the reasons.
Therefore,improving the aging resistance, adhesion, flexibility, and other properties of EIFS adhesives has attracted attention.
Polymer based cementitious adhesive is a new adhesive in the field of building exterior wall insulation. It has obvious advantages with high density, good aging resistance and good adhesion.
The Importance of EIFS Adhesive
As a high-performance polymer-modified cement adhesive, it is made with high-grade aggregates, cement and polymers. Among which, HPMC (Hydroxypropyl Methyl Cellulose) plays vital roles in it. It is with good performance of water retention, high strength and can increase the bonding strength between the insulation plate and exterior wall.
EIFS adhesive is a very practical adhesive, not only the adhesive itself must have excellent performance, it is also necessary to cooperate with appropriate construction techniques to achieve good results.
