At this year’s PAINTINDIA, WACKER will be presenting two dispersible polymer powders for formulating tile adhesives that will soon be introduced into the growing Indian market.
Improve Workability of Tile Adhesives
When added to dry-mix mortars,
VINNAPAS® 4419 E and
VINNAPAS® 8819 E produce a creamy consistency which makes the resulting product easier to use. The PAINTINDIA International Exhibition & Conference will be held in Mumbai, India, from February 22 to 24.
“
India is one of the largest construction markets in Asia. With our dispersible polymer powders, we mainly cater to the growing demand and needs of the construction industry. Skim coats as well as tile adhesives are top-sellers, just to name two examples. We are continuously working on enhancing our products and providing technical expertise and customer service along the value chain. At PAINTINDIA, we will be presenting a range of new products for the Indian market”, says Anand Gopaladesikan, responsible for WACKER’s polymers business in India.
The dispersible polymer powders are geared primarily towards improved workability and were developed specifically with users in mind, i.e., tilers and other skilled workers. For them, proper mortar consistency is key, when both mixing the dry-mix mortar with water and then applying the fresh mortar. The creamier and smoother a tile adhesive is, the less physical effort required to apply it and the more pleasant it is for users to handle.
Benefits of VINNAPAS® 4419 E & VINNAPAS® 8819 E
The new VINNAPAS® 4419 E and VINNAPAS® 8819 E polymeric binders have been modified in such a way that the viscosity of fresh mortar is lowered by up to 20 percent. As a result, less physical effort is required for preparing the mortar and applying it with a notched trowel. Realistic assessments carried out on test walls have demonstrated that this makes using it much easier.
The VINNAPAS® products also improve open time and correction time – in other words, the period in which the tiler can still adjust a tile’s position before the adhesive sets and hardens. This improvement is particularly noticeable in warmer regions with more sunlight, where tilers will now have more time to prepare fresh mortar, even at high ambient temperatures.
Tilers are not the only ones who stand to gain from the polymeric binders – the producers of tile adhesives will benefit as well. The favorable processing properties of these types of mortars mean that, in some cases, producers will need far fewer additives or even be able to dispense with them entirely.
Suitable for Demanding Applications
VINNAPAS® 4419 E and VINNAPAS® 8819 E were developed for tile adhesive formulations. In addition to making mortar easier to use, these binders also boost the non-sag properties of the mortar bed. Tilers can shift, adjust and ultimately fix tiles into place without major physical effort.
At the same time, the new dispersible polymer powders optimize the degree of wetting on the back of the tile – an especially important feature for working with porcelain tiles or large slabs and for creating a secure, permanent bond between these materials and the substrate. VINNAPAS® 8819 E was developed specifically with the most demanding applications in mind.
WACKER will give live demonstrations of applications ranging from skim coat/wall putty to cementitious tile adhesives and waterproofing membranes. Experts will be on hand every day at the WACKER booth to demonstrate the compelling benefits of WACKER products in tile adhesives, and skim-coat and one-component waterproofing applications.
