Brief Overview on Bio-Based Adhesives and Sealants

Polyurethane Adhesives and Sealants Based on Hydrophobic Polyols

Thermosetting polyurethane polymers are staples of adhesive and sealant formulations used in a variety of industrial applications. Polyurethane materials generally provide reliable service under most application conditions, but the long-term performance and durability of some polyurethanes can be compromised by direct and prolonged contact with bulk water or high ambient humidity. The Dow Chemi...

Bio-Based Feedstocks for Adhesives and Sealants: Everything Old is New Again

Effects of Self-etch Adhesives on Microleakage of Fissure Sealants

Background and Aim: The aim of this study was to evaluate the microleakage of fissure sealants placed with different

Bio-Based Adhesives and Evaluation for Wood Composites Application

There has been a rapid growth in research and innovation of bio-based adhesives in the engineered wood product industry. This article reviews the recent research published over the last few decades on the synthesis of bio-adhesives derived from such renewable resources as lignin, starch, and plant proteins. The chemical structure of these biopolymers is described and discussed to highlight the ...

A Brief Overview of Epilepsy with Emphasis on Children

Epilepsy is a brain disorder in which a person has repeated seizures over time. A seizure is a sudden change in the electrical and chemical activity in the brain. A single seizure that does not happen again is NOT epilepsy. Most children with epilepsy live a normal life. Certain types of childhood epilepsy go away or improve with age, usually in the late teens or 20s. Nearly 80% of people with ...
