    SIS copolymer is largely used in hot melt pressure sensitive adhesive applications. Tackifier is selected based on solubility parameter approach qualitatively. Practically, error will occur for different reasons. Tackifier’s existence in the two phase of SIS copolymer needs to study quantitatively. In this paper, clarity is used to identify the solubility of tackifier in representative polystyrene and polyisoprene. Test shows this method can describe the behavior of different tackifiers in this two polymers. It can be an efficient method for further investigation of tackifier’s behavior in different SIS copolymer, and hence, supports the formulation in hot melt pressure sensitive adhesive application.…

    Japan Adhesive Industry Association (JAIA) is an organization with a history of 52 years now. As the market changes rapidly, JAIA is managed by more than 10 committees in order to respond such changes. At this presentation, we would like to share the information about recent market trends in Japan and the major activities operated by each committee. The Technical Committee and the Safety and Environment Committee pioneered the issue of indoor air pollution ahead of the rest of Asia and cooperated with the establishment of the Japanese Industrial Standards. JAIA established own two registration systems. One is F ☆ ☆ ☆ ☆ mark system corresponding to the formaldehyde regulation and the other is 4 VOCs voluntary control system corresponding to the four kinds of VOC regulation. The registration system become de facto standard and has been widely recognized as best index for applying adhesive in door. On another front, Educational Committee has established unique education system in order to use adhesives appropriately. Original text book is a hidden great book for people who are engaged in this business field. Further JAIA activities will be presented. …

    Academia and industry have extensively studied the utility of blocked isocyanates because blocked isocyanate technology allows 1K polyurethane and 1K/2K epoxy systems to achieve safer processes and higher performance coatings and adhesives. Key improvements include reduced free isocyanates and extended storage stability, specially for one component formulations, by minimizing moisture sensitivity through masking the isocyanate. Commonly used isocyanate blocking agents include phenol, nonyl phenol, and some other agents. The structure of the blocking group has major impact on deblocking temperature and cure rate of the coating or adhesive. Due to raised health concerns over phenols and nonyl phenol (NP), industries have requested for non-toxic alternatives with similar performances and benefits. Cardanols from cashew nutshell liquid have been investigated as non-toxic alternative and have shown lower deblocking temperature than NP and phenol and excellent stability at room temperature. Cardanol and NP blocked prepolymer systems were tested in epoxy systems cured with phenalkamines for its bond strength, mechanical properties, and cure speed along with moisture resistance. In this presentation, we will discuss detailed results and advantages of using Cardanol as a replacement of phenol and nonyl phenol. …

    We have been developing environmentally friendly water-borne tackifiers for adhesives. In this market, the need for environmentally responsible products has increased. This increase has been driven both by the end-users requirements and through both local and global regulations. To balance the environmental impact and maintain or enhance performance, requirements for emulsion tackifiers have also been evolving. Our high softening point emulsions show excellent performance, so it can expand applications of water-borne PSA and replace solvent based PSA. We would like to give a presentation on the emulsion characteristics and recent unique developments to meet current and future requirements.…

    Fumed silica is an all-round product widely employed in the chemical industry. Yet, despite being in everyday contact with it, consumers are usually unaware of its presence. In principle, HDK® – WACKER’s trade name for pyrogenic silica – is nothing more than a hyperpure, amorphous form of silica that has a high surface area and low density. Since the application-specific characteristics required of adhesives and sealants can vary considerably, HDK® has been developed with an equally varied range of talents. Whether for individual rheological properties, reinforcement or thickening, this highly dispersed pyrogenic silica can provide the solution to achieve remarkable results in every respect. …

    Pressure Sensitive Adhesive (PSA) is a widely used adhesive that attaches to various substrates without chemical reaction. The cohesion and adhesion of PSA are subject to the balance of viscoelastic properties that are affected by diverse control factors of PSA such as glass transition temperature (Tg), polymer morphology and monomer composition. In particular, environmentally friendly water based PSA is of great interest to the industry in that the organic solvents are not used, and its importance in the market is significantly increasing over the decades. Water based PSA is generally prepared by emulsion polymerization, which is widely used polymerization technology due to easy control of reaction heat and high consistency of polymer quality. Since PSA is usually supplied in the latex form, it is easy to apply to the process and storage and transportation is convenient. Especially PSA latex with high solid content is advantageous in terms of productivity and cost saving because of its low energy cost for drying. However, higher solid content typically increases the viscosity of the PSA latex, which makes the application process difficult as well. Therefore, it is crucial to overcome the trade-off relationship of solid content and viscosity. Possibly control of particle size and its distribution could be a feasible approach to this huddle, which includes three methods: 1) latex blending, 2) 2-step seed polymerization for bimodal size, 3) 1-step polymerization with broad size distribution.Formulation, mixing of the ingredients including additives, is also very important to improve the physical property and adhesion of PSA. Additives such as wetting agent, thickener, plasticizer and defoamer can facilitate the application of the coating process by balancing the PSA properties. Addition of tackifier, which usually has low molecular weight and high Tg, is also very effective in enhancing adhesion properties after polymerization of PSA. …
