Elvacite® acrylic resins are polymers or copolymers of methyl methacrylate or other acrylic monomers for use in solvent-applied lacquers, inks, adhesives and specialty coatings. Elvacite® acrylic resins offer the distinctive combination of properties associated with high-quality coating resins.
ATP2G (2nd Generation ATP) allows users to measure quantitative microbial content in really every sample and this in just a few minutes. From water to chemical-complex materials, surfaces and solids. In Europe there are already hundreds of companies in coating application that use ATP2G. In particular for entry control but also for plant-hygiene. ATP2G is not only lightning-fast, but also far more accurate than traditional test method. Certainly, when it comes to biocide performance analyses, ATP2G offers superior, fast and accurate microbial insight.
Foam is a dispersion of air and other gases in a liquid or solid. Apart from a few exceptions (foams in shampoos, shaving creams, hair styling mousses, carpet cleaners, polyurethane or other polymers that insulate homes) foams are generally undesirable. Foams disturb production sequences in which liquids, particularly water, have an important function as transporting media, and in the worst cases they can even bring such processes to a standstill. Furthermore, foams can lead to lower production yields and finished products of poorer quality.
Tennanol surfactant is a wetting agent and molecular defoamer that provides a unique combination of performance benefits. Tennanol surfactant’s unique chemical structure allows this product to provide multifunctional properties such as surface tension reduction, foam control, and viscosity stabilization. The hydrophobic nature of Tennanol surfactant typically results in significantly reduced water sensitivity compared to either conventional ethoxylated or anionic surfactants.
Polyvinyl acetate is processed in the form of solutions in organic solvents or as a dispersion.
About 40 % solids water based acrylic dispersion special developed for water based inks with a high TG, self-crosslinking mechanism for improved adhesion, showing good hardness and chemical resistances.
Hardeners are basically liquid resins with amino nature that can react with the oxiranic ring of the epoxy resin giving a solid product with high molecular weight. The hardeners are characterized by their hydrogen equivalent (HEW), that is the weight in grams needed to have one reactive hydrogen atom. From this parameter we can calculate the so called PHR (per hundred ratio), that is the weight of hardener that we need for a stechiometric reaction with 100 grams of epoxy resin.
Tennants presents a class of very versatile thermosetting products thanks to their outstanding chemical-physical characteristics. There are a number of properties of Epoxy Resin Systems that influence the choice over other technologies in its application:
Low shrinkage and very good dimensional stability, can be easily fabricated. Good thermal properties, good physical properties such as toughness, flexibility and abrasion resistance, strong adhesive power on various substances, high reactivity allows good hardening at low temperature
Halogen-free, phosphorus- and nitrogen-based intumescent flame retardant (IFR). Good compatibility, stable flame retardancy and excellent migration resistance. Offers good heat yellow stability and processability. Specially developed for polyolefin (PE, PP), but is also suitable for use in thermoplastic elastomer (TPE, TPU), EVA, and rubber.
It is used as a binder in coatings and varnishes. Further use is the plastic as a white glue (wood glue), wallpaper supplier or adhesive. The universal adhesive UHU, known in Germany, is a forty percent solution of polyvinyl acetate in acetone and methyl acetate. Even simple craft glue often contains predominantly PVA and is then referred to as vinyl glue, among other things.
Organofunctional silanes are compounds that combine the functionality of a reactive organic group with inorganic functionality in a single molecule. This special property allows them to be used as molecular bridges between organic polymers and inorganic materials. This bridging property of organofunctional silanes is crucially important in four application fields:
- adhesion promotion
- surface modificatio
- crosslinking of polymer
Silicone emulsions typically contain a silicone component (usually a silicone oil), water and the required emulsifiers to obtain a stable emulsion. From the chemistry perspective, a silicone component is a finite chain of silicone and oxygen atoms bonded to each other. Besides these bonds, silicone itself has two other bonds to organic groups. In most cases, these components are methyl groups (CH3) that provide to the silicone component its characteristic semi-organic behaviour.
Tannin stain blocking additives were developed to augment resin technology in stopping the migration of these soluble stains to the surface of the paint. Blocking tannins and other common wood stains (sap, rosin or other oleo resinous substances) can be quite daunting for water-based coatings. TenADD stain blockers come as liquid additives which are formulated into paint where they are designed to react with soluble tannins to form insoluble complexes.
Titanium dioxide (TiO2) is the most widely used white pigment in the world. It’s the mainstay of our range and we are proud to be a front-runner in this highly specialized sector. Titanium is the 9th most abundant element in the world and titanium dioxide is the oxide of the metal, which occurs naturally in two main forms: rutile and anatase. It is then processed to remove any impurities, creating an incredibly useful, multi-purpose, white pigment. Odourless and absorbent, TiO2 has a high refractive index – meaning it has excellent light scattering capabilities. Ideal for inclusion in a variety of consumer and industrial products, TiO2 is particularly well suited to applications that need to deliver high levels of opacity, brightness and ultraviolet (UV) protection.
